Risk of SCA according to ∆FBG. A significant association between ∆FBG and SCA risk was present in the whole cohort. That association was mainly observed in the DM group. People without DM did not show a clinically significant association between ∆FBG and SCA. DM, diabetes mellitus; FBG, fasting blood glucose; SCA, sudden cardiac arrest. Hazard ratios were adjusted for age, sex, body mass index, smoking status, alcohol consumption, regular physical activity, income level, hypertension, dyslipidemia, chronic kidney disease, heart failure, baseline FBG (measured in 2009), and DM duration (for diabetic group only; new-onset DM, DM for < 5 years, and DM for ≥ 5 years)
